DESCRIPTION OF EMBODIMENTS

In the present invention, a body waste treating material can bemanufactured from a defective fibrous material unsuitable for formingpaper, and an object of providing the body waste treating materialwithout water absorbing agent as a material for complementing waterabsorptive property and a water retention property separately and auseless step in manufacturing simply and easily at a low cost, andefficiently using resources, and being well dissolved and flown intodrainage to be easily discarded, and being environment-friendly with ahigh water absorptive property, and reducing weight is achieved by usingthe pulpable raw material such as used paper.

Embodiment

FIGS. 1-17 show embodiments of the present invention. As shown in FIG.2, an apparatus 1 for manufacturing a body waste treating material Fincludes a disintegrator 2, a deinking machine 3, a dehydrator 4, ableaching machine 5, a classifying machine 6, and a molding machine 7,in which the body waste treating material F is manufactured using apulpable raw material. In the present embodiment, used paper A is usedas the pulpable raw material.

As for the pulpable raw material, pulp itself can be used without usingthe used paper.

The disintegrator 2 includes agitating blades, adds, for example, waterto used paper A as the pulpable raw material, and disintegrates the usedpaper A to generate a dissolved material B.

The deinking machine 3 deinks the dissolved material B generated by thedisintegrator 2. The dehydrator 4 dehydrates the dissolved material Bdeinked by the deinking machine 3 to generate a fibrous material C. Thebleaching machine 5 bleaches the fibrous material C generated by thedehydrator 4. The classifying machine 6 classifies the fibrous materialC (also referred to as “pulp”) bleached by the bleaching machine 5 intoa non-defective fibrous material D (also referred to as “wet” or“pulpa”) suitable for forming paper and a defective fibrous material E(also referred to as “sludge”) unsuitable for forming paper.

The molding machine 7 molds the defective fibrous material E unsuitablefor forming paper generated by the classifying machine 6 to form thebody waste treating material F with a certain shape.

In the defiberizing step of the used paper A, the fibrous material Ccontaining therein fibers having a variety of thicknesses and lengths isgenerated. In forming paper, since the fibers are entwined and thinlymolded, fibers with a thick and/or a long property are suitable. As forshort fibers with a thin and/or a short property, however, since theyare hard to be entwined and unsuitable for forming paper, they areusually discarded. Accordingly, the fibrous material C includes thenon-defective fibrous material D formed by the fibers with a thickand/or a long property suitable for forming paper and a defectivefibrous material E formed by the fibers with a thin and/or a shortproperty unsuitable for forming paper.

Accordingly, the classifying machine 6 classifies the fibrous material Ccontaining therein fibers with different properties into thenon-defective fibrous material ID suitable for forming paper and thenon-defective fibrous material E unsuitable for forming paper using afilter.

In the classifying step according to the present embodiment, forexample, a filter with a slit having a width (size) of 0.15 mm is usedto classify the fibrous material C into the non-defective fibrousmaterial D with a fiber diameter greater than 0.15 mm, which remains onthe filter and the defective fibrous material E with a fiber diametersmaller than 0.15 mm, which passes through the filter.

This numeral value tends to be adopted relatively frequently.

Accordingly, the numeral value of the fiber diameter in the presentembodiment is merely an example and does not limit a scope of thenumeral values.

Next, a method for manufacturing the body waste treating material F isdescribed.

As shown in FIG. 1, upon manufacturing the body waste treating materialF, first, the used paper A as a pulpable raw material is prepared, andthe body waste treating material F is manufactured according to thesteps of defiberizing, deinking, dehydrating, bleaching, classifying,and molding.

As for the pulpable raw material, pulp itself can be also prepared.

Upon manufacturing the body waste treating material F, first, in thepreparing step (step S1), the used paper A as a material is prepared anda foreign material is removed from the used paper A.

In the defiberizing step (step S2), water and necessary agents (such assodium hydroxide, hydrogen peroxide, sodium silicate) are added to theused paper A to be fed into the disintegrator 2 and agitated accordingto rotation force of the agitating blades rotating at a high speed tomix the water with the used paper A and disintegrate the used paper A soas to generate dissolved material B (step S3).

In the present embodiment, in principle, refining beating used forforming paper is not performed. Accordingly, the fibers are notcompressed in vain so that the fibers are maintained as flexible.Namely, the fibers themselves are not compressed, and the fibers tangledwith each other are not compressed as well. Accordingly, upon formingthe body waste treating material F, porosity in an inside thereof can beincreased and a water absorptive property can be improved.

In this step S3, the refining beating may be performed on thedisintegrated fibers according to the needs.

In the deinking step (step S4), the dissolved material B generated inthe defiberizing step (step S2) is deinked using air bubbles in thedeinking machine 3. In this case, deinking agent (chemical agent) isadded into the deinking machine 3 to swell the dissolved material B soas to allow an ink to be dissolved from and be come off the fibers.

In the dehydrating step (step S5), the dissolved material B deinked inthe deinking step (step S4) is dehydrated by the dehydrator 4 togenerate the fibrous material C (step S6). In this dehydrating step(step S5), most of moisture in the fibrous material C is removed, but acertain amount of moisture is contained in the fibrous material C.

In the bleaching step (step S7), bleach (such as sodium hypochlorite,chlorine dioxide, and hydrogen peroxide) is added to the fibrousmaterial C generated in the dehydrating step (step S5) to be fed intothe bleaching machine 5 to be bleached. According to the bleach, thefibrous material C is decolorized to be substantially white as a whole.

In the classifying step (step S8), the fibrous material C bleached inthe bleaching step (step S7) is classified into the non-defectivefibrous material D suitable for forming paper and defective fibrousmaterial E unsuitable for forming paper by the classifying machine 6(step S9).

Upon this, in the classifying step, a filter with a slit having a width(size) of 0.15 mm, for example is used to classify the fibrous materialC into the non-defective fibrous material D with a fiber diametergreater than 0.15 mm, which remains on the filter and the defectivefibrous material E with a fiber diameter smaller than 0.15 mm, whichpasses through the filter.

This numeral value tends to be adopted relatively frequently.

Accordingly, the numeral value of the fiber diameter in the presentembodiment is merely an example and does not limit a scope of thenumeral values.

The defective fibrous material E classified by the classifying machine 6is colored paler than the white non-defective fibrous material D and thedefective fibrous material E includes an amount less than a large amountof the non-defective fibrous material D.

In the molding step (step S10), the defective fibrous material Eclassified in the classifying step (step S8) is molded by the moldingmachine 7 to form a dry body waste treating material F with a certainshape (step S11).

In this molding step (step S10), the defective fibrous material E is,for example, packed into the mold to form the body waste treatingmaterial F with a certain shape, or the defective fibrous material E isextruded through a mold cavity by an extruding mechanism to form thebody waste treating material F with a certain shape.

According to the present embodiment, this body waste treating material Fis formed to have a diameter of about 5 mm and a length of about 5-10mm. The size of the body waste treating material F is, however, notlimited to the above size.

By forming this molded body waste treating material F to have a diameterof about 5 mm and a length of about 5-10 mm, for example, the body wastetreating material F may have a high internal porosity, a high waterabsorptive property, and a high resolvability upon absorbing water froma body waste. Thus, the body waste treating material F is easilydissolved by the body waste so as to be easily aggregated by beingadhered to each other.

Further, since this body waste treating material includes a highinternal porosity, weight per unit is small, namely it includes a lightproperty. Accordingly, it can be easily conveyed.

Moreover, this body waste treating material F is used by being put intoa container configuring a toilet for a pet or a simple toilet upondisasters, for example. In this case, since the body waste treatingmaterial F is of light weight, it is easy to convey the toilet.

Also, in the body waste treating material F used and aggregated byabsorbing water, since the fibers are easily disintegrated with a highresolvability, the body waste treating material F does not clog pipingand flows smoothly. Accordingly, the body waste treating material can beflown into drainage to be discarded without an incinerating process or adissolving process, for example. Therefore, loads on an environment canbe reduced, and thus the body waste treating material isenvironment-friendly.

In the present embodiment, in the process of manufacturing the bodywaste treating material F, the steps of defiberizing, deinking,dehydrating, bleaching, and molding are performed in this order, butthese steps can be interchanged to be reordered.

Further, in the process of manufacturing the body waste treatingmaterial F, it is possible to perform the step of agitating the fibersor pulverizing the fibers.

As shown in FIGS. 3-17, in the molding step, the body waste treatingmaterial F with a shape including a variety of types of properties canbe formed.

As shown in FIG. 3, for example, in the molding step, a body wastetreating material F1 with a short bar columnar shape can be formed.

Since the shape of the body waste treating material F1 with this shortbar columnar shape is simple, manufacture thereof is easy and it can bemanufactured easily at a low cost.

As shown in FIG. 4, in the molding step, a body waste treating materialF2 with a short curved columnar shape can be molded. This short curvedcolumnar body waste treating material F2 is entwined with each other inthe container of the toilet so that it does not fly out of the containerduring a use by a pet, and the body waste does not reach a bottom of thecontainer through the body waste treating material F2. Accordingly,absorption of the body waste is excellent.

As shown in FIG. 5, in the molding step, a body waste treating materialF3 with a spherical shape can be formed. Even if the pet steps on thisspherical body waste treating material F3 in the container of the toiletfor a pet, the pet is not reluctant to relieve nature so that it is easyto have the pet learn the way to use the toilet.

As shown in FIG. 6, in the molding step, a body waste treating materialF4 with a spherical surface on which recesses R are formed can beformed. In this body waste treating material F4 with the surface onwhich the recesses R are formed, the recesses R are easy to receive thebody waste, and the body waste treating material F4 includes a highabsorbing property according to an enlarged surface area.

As shown in FIG. 7, in the molding step, a body waste treating materialF5 with a spherical surface on which protrusions P are formed is formed.A surface area of this body waste treating material F5 with the surfaceon which the protrusions P are formed is enlarged by the protrusions Pso that the body waste can easily set and the body waste treatingmaterial F5 can be piled up to reduce an amount of use thereof.

As shown in FIG. 8, in the molding step, a body waste treating materialF6 with a spindle shape can be formed. The body waste treating materialF6 with the spindle shape may be closely arranged with the body wastetreating material F6 adjacent to each other and put into the containerof the toilet. Further, the body waste does not reach the bottom of thecontainer through the body waste treating material F6. The body wastetreating material F6 can absorb the body waste well.

As shown in FIG. 9, in the molding step, a spherical body waste treatingmaterial F7 with a hollow C in an inside thereof is formed. Since thisbody waste treating material F7 with the hollow C in the inside thereofis of light weight according to the hollow C, it is easily conveyed andcan absorb the body waste well.

As shown in FIG. 10, in the molding step, a triangular star shaped bodywaste treating material F8 on which three legs t1-t3 protruding in threedirections in a plan view are formed can be formed. A surface area ofthe triangular star shaped body waste treating material F8 with thethree legs t1-t3 can be enlarged by the legs t1-t3 to improve anabsorbing property, and the legs t1-t3 entwine with each other uponbeing fed into the container to include space therebetween. Accordingly,the body waste treating material F8 can be of light weight with respectto a volume thereof, and easily conveyed.

As shown in FIG. 11, in the molding step, a dual-structured body wastetreating material F9 with a central side having the defective fibrousmaterial E and an outer peripheral side having the non-defective fibrousmaterial D can be formed. In the body waste treating material F9 withthe dual structure of the defective fibrous material E and thenon-defective fibrous material D, the water absorptive property and thewater retention property can be further improved by the non-defectivefibrous material D on the outer peripheral side.

As shown in FIG. 12, in the molding step, a wave dissipating blockshaped body waste treating material F10 on which legs t1-t4 protrudingin four directions are formed can be formed. A surface area of the bodywaste treating material F10 with the four legs t1-t4 can be enlarged bythe legs t1-t4 to improve an absorbing property, and the legs t1-t4entwine with each other upon being fed into the container to includespace therebetween. Accordingly, the body waste treating material F10can be of light weight with respect to a volume thereof, and easilyconveyed.

As shown in FIGS. 13 and 14, in the molding step, a body waste treatingmaterial F11 with a high internal porosity can be formed.

As for this body waste treating material F11, in the molding step, forexample, the defective fibrous material E is preformed by a mold (stepS21), and this preformed defective fibrous material E is expanded(decompression controlled) in a decompression container (step S22).

This decompression control includes a vacuum state and is performedbetween the vacuum state and an atmospheric pressure. Further, thedecompression control may be performed rapidly or moderately.

In the decompression control of the defective fibrous material E, apressure in the decompression container is controlled so that thedefective fibrous material E (as shown in FIG. 13(A)) preformed to havea small diameter first is expanded to be the body waste treatingmaterial F11 (as shown in FIG. 13(B)) as a spherical fibrous materialwith a certain diameter.

As the preformed defective fibrous material E is expanded to be the bodywaste treating material F11 (as shown in FIG. 13(B)) as a sphericalfibrous material with a certain diameter as described above, many piecesof air are present in the inside of the body waste treating material F11to have a high internal porosity.

In this case, it is possible to heat the defective fibrous material E byheating means or humidify the defective fibrous material E byhumidifying means to complement water according to the needs so that thedefective fibrous material E with fibers having small diameters iseasily expanded in a state where the fibers are tangled with each other.

Then, the non-defective fibrous material D is taken out of thedecompression container to form the body waste treating material F11dried without moisture, which is of light weight, and has a high waterabsorptive property (step S23).

As shown in FIGS. 15 and 16, in the molding step, a body waste treatingmaterial F12 with a flexible outer surface and a high water absorptiveproperty can be formed.

As for this body waste treating material F12, in the molding step, thedefective fibrous material E is preformed by a mold (step S31), anadhesive is applied to a surface of this preformed defective fibrousmaterial E (step S32), and then, a surface fiber k is attached to thesurface of the defective fibrous material E to form a flexible layer N(step S33).

The surface fiber k forming the flexible layer N is the non-defectivefibrous material D and/or defective fibrous material E, for example asfibers in a detangled state.

Regarding an operation for attaching the surface fiber k onto thedefective fibrous material E, for example, detangled surface fiber k islaid on a plate, and the preformed defective fibrous material E isrolled over the plate to attach the detangled surface fiber k onto thesurface thereof.

Thereby, on the surface of the defective fibrous material E, theflexible layer N with a high water absorptive property is formed so thatthe body waste treating material F12 with a flexible outer surface and ahigh water absorptive property can be formed (step S34).

Further, the number of times of attaching the surface fibrous material konto this defective fibrous material E may not be limited to once butseveral to form a multilayered structure so that a thickness of theflexible layer N of the defective fibrous material E can be enlarged.

Further, the attachment of the surface fiber k may be applied to theabove described respective body waste treating materials F-F11.

As shown in FIG. 17, in the molding step, a body waste treating materialF13 having a high water absorptive property, while maintaining a profilethereof can be formed. As shown in FIGS. 15 and 16, in this body wastetreating material F13, the flexible layer N formed by the surface fiberk itself is maintained in a flexible state, while merely a surface ofthe flexible layer N is hardened by a hardener, for example to form ahardened surface H. The body waste treating material F13 with theflexible layer N having a surface on which the hardened surface H isformed maintains its profile by the hardened surface H on the surface,while a water absorptive property can be improved by the flexible layerN with flexible contents and the body waste treating material F13 may beof light weight with respect to a volume thereof so that it can beeasily conveyed.

As a result, the body waste treating material F according to the presentembodiment is manufactured by molding the defective fibrous material Eunsuitable for forming paper that is a fibrous material C obtained bydefiberizing, dehydrating, and bleaching used paper A as a pulpable rawmaterial to a certain shape.

Since the body waste treating material F according to the presentembodiment is manufactured by using the defective fibrous material Egenerated upon treating the used paper A, it can be manufactured easilyat a low cost without separate materials for complementing a waterabsorptive property and a water retention property and a wasting stepfor mincing corrugated paper as a raw material as in a conventionalstep. Further, since the body waste treating material F is manufacturedby using the defective fibrous material E generated upon treating theused paper A, resources can be efficiently used.

Moreover, in the body waste treating material F, the porosity in aninside of each of the fibers can be improved and the body waste treatingmaterial F includes a high water absorptive property and can be of lightweight, and the defective fibrous material E with thin and short fibersare easily disintegrated into water and has a high resolvability so thatit can be flown into drainage to be easily discarded. Accordingly, thebody waste treating material F is environment-friendly.

Also, this body waste treating material may be manufactured by amanufacturing apparatus 1 with a simple structure.

The present invention is not limited to the above described embodimentbut can be modified for a variety of applications.

For example, in the above described embodiment, the used paper A isillustrated as a pulpable raw material, but materials such as wood asvirgin pulp (e.g., a needle-leaved tree and a broad-leaved tree) ornon-wood pulp (such as linter and kenaf), and synthetic fiber (e.g.,chemosynthetic fiber) may be used solely, or a plurality of thematerials may be combined to be used. These materials may be pulped by amechanical system using a mechanical device, or a chemical system usingagents.

In the above described embodiment, the fibrous material C is classifiedinto the non-defective fibrous material D and the defective fibrousmaterial E by a filter of the classifying machine 6, but the defectivefibrous material E can be classified according to a pressurizedflotation method using pressurized air, a precipitation method usingaggregating agent, and a ore floatation method using air bubbles, forexample. In the present embodiment, a filter with a slit having a width(size) of 0.15 mm, for example is used to classify the fibrous materialC into the non-defective fibrous material D with a fiber diametergreater than 0.15 mm, which remains on the filter and the defectivefibrous material E with a fiber diameter smaller than 0.15 mm, whichpasses through the filter.

This numeral value tends to be adopted relatively frequently.

Accordingly, the numeral value of the fiber diameter in the presentembodiment is merely an example and does not limit a scope of thenumeral values.

In the above described embodiment, the body waste treating material F ismanufactured by the defective fibrous material E generated by processingthe used paper A, but the body waste treating material F may bemanufactured by using a fibrous material (sludge) obtained byaggregating and settling paper industry drainage water with agent(aggregating agent) from which heavy metals are removed.

Also, in manufacturing the body waste treating material F, as shown by adashed line in FIGS. 1 and 2, prior to the molding step (step S10), amixing step (step S9-1) of complementarily mixing the non-defectivefibrous material D suitable for forming paper with the defective fibrousmaterial E unsuitable for forming paper by a mixing machine 8 may beperformed.

By complementarily mixing the non-defective fibrous material D with thedefective fibrous material E, color of the manufactured body wastetreating material F may be whitened and the smell is reduced so as toimprove quality thereof.

Further, since the defective fibrous material E with the thin and shortfibers is easily disintegrated into water and has a high resolvability,an amount of the non-defective fibrous material D to be mixed with thedefective fibrous material E can be limited.

Moreover, as the non-defective fibrous material D to be complementarilymixed with the defective fibrous material E, wood (e.g., a needle-leavedtree and a broad-leaved tree), non-wood (such as linter and kenaf), andsynthetic fiber system (e.g., chemosynthetic fiber) descried above maybe pulped and one, two, or more types of them may be mixed to be used.

Furthermore, to control emission of smell after use, an air refreshermay be added to the defective fibrous material E, and to allow thedefective fibrous material E to be easily hardened upon absorbing water,an adhesive may be added thereto. To notify a user of absorbing water,dye may be added as well.

Also, in manufacturing the body waste treating material F, as shown byan alternate long and short dash line in FIGS. 1 and 2, after themolding step (step S10), a coating step (step S12) of coating the moldedbody waste treating material F with the non-defective fibrous material Dby a coating machine 9 may be performed.

Accordingly, as shown in FIG. 1, upon manufacturing the body wastetreating material F, in the coating step (step S12), a coated body wastetreating material Fc may be obtained (step S13) by coating a surface ofthe body waste treating material F molded from the defective fibrousmaterial E with the white non-defective fibrous material D withoutsmell.

In the body waste treating material Fc with a surface coated with thenon-defective fibrous material D, the defective fibrous material E isnot exposed to the surface, and the surface can be whitened to improvean appearance and leakage of smell of the defective fibrous material Ecan be controlled.

Also, to the non-defective fibrous material D used in the coating step,the air refresher may be added to control the emission of the smellafter use, and the adhesive may be added to allow the body wastetreating material to be easily hardened by absorbing water, or the dyemay be added to notify the user of absorbing water.

Further, in the method for manufacturing the body waste treatingmaterial F, to increase a degree of whiteness, calcium carbonate may bemixed with the fibrous material.

Moreover, a micro bubble generator for generating micro bubbles (fineair bubbles) may be added to the manufacturing apparatus 1 and a step ofallowing the fibrous material C to contain the micro bubbles generatedby the micro bubble generator may be added to the manufacturing methodso as to increase internal porosity of the body waste treating materialF.

Accordingly, the manufactured body waste treating material F may be oflight weight and easily conveyed with an improved water absorptiveproperty to be easily coagulated to be a mass and be easilydisintegrated by water to have a high resolvability to be flown intodrainage to be easily discarded and be environment-friendly. Further, anamount of use of the defective fibrous material E may be saved so thatthe body waste treating material F can be manufactured at a low cost.
